Abstract

We demonstrate a simple image-based method to measure pressure in microsystems using volume displacement of fluorescent particle suspensions. This pressure sensing method has high precision when operated in both the direct and the remote detection modes. These simple sensors have the advantage that a broad sensing range can be achieved by tuning the focal plane or the pressure of a reference chamber without re-design or re-fabrication. In addition, the image analysis using the software code developed here is fast, and generates data simple to interpret.
